What are Colouring Foodstuffs?

Colouring Foodstuffs are food ingredients used by the food industry for the primary purpose of imparting colour to food and beverage products.

They are manufactured from fruits, vegetables, flowers, spices, algae and/or other edible source materials. Colouring Foodsuffs are considered ‘Clean-Label’ ingredients, and offer an alternative to using colours as food additives in a wide variety of food applications. They appeal to producers/customers who want a food product which is based on ingredients that consumers can easily relate to.

The criteria for a food extract with colouring properties to be classified as Colouring Foodstuffs (and not as food colour additive) are:

  • The primary extract is added during the manufacturing of compound foods with the primary effect to deliver colour to the compound food. If the primary extract is used because of its aromatic, sapid or nutritive properties together with a secondary colouring effect, the primary extract is either a food or a flavouring;
  • The source material must be a food or a characteristic ingredient of food which is normally consumed as such within the EU;
  • The pigments present in the source material must NOT undergo selective, physical and/or chemical extraction relative to the nutritive and aromatic constituents. 

Where a Colouring Food is used in a food product, its function is not required on the labelling. Instead it is listed as an ingredient. For example: “Fruit and Vegetable Extracts (Radish Concentrate, Apple Concentrate, Blackcurrant Concentrate)”

These criteria are defined in the EU Guidance notes on the classification of food extracts with colouring properties (29.11.2013, Version 1), which was adopted by the European Standing Committee on the Food Chain and Animal Health.

The Guidance Notes provide a working tool for business operators and enforcement authorities to consider whether a substance is a food colour additive or a “Colouring Food”. The EU Guidance Notes include a decision tree (Annex I) and a checklist (Annex II) to facilitate the classification. The reference values for the source materials (Annex III) remain to be completed and NATCOL continues to support this work.

Labelling of Colouring Foodstuffs must be in accordance with Food Information Regulation (EU) No 1169/2011. The labelling needs to be clear and understandable to the consumer and should not be misleading. However, the labelling must be assessed case-by-case by the food manufacturer. Possible labelling on the ingredient list of the final food within the EU are for example “Colouring Food (Carrot Concentrate)” or “Red Beet Concentrate”.

Colouring Foodstuffs do not need to be designated like food colour additives, i.e. by the name of their category “Colour” and an E-number.

WHAT ARE NATURAL COLOURS?

Natural Colours used in the food industry originate from a wide range of sources like vegetables, fruits, plants, minerals and other edible natural sources. They impart colour when added to food or drink.

Natural Colours are preparations obtained from foods and other edible natural source materials obtained by physical and/or chemical extraction, resulting in a selective extraction of the pigments relative to the nutritive or aromatic constituents.

The use and labelling of Natural Colours colours as food additives is governed by the EU Legislation 1334/2008. Where a Natural Colour is used, its function must be declared on the product labelling. For example, ‘Colour: E160a’ or ‘Colour: Beta Carotene’. Natural Colours tend to have higher concentrations of the active pigments meaning a more intense colour, as well as being more stable in a wider variety of applications.

Carotenes E160a

E160a (i) Synthetically derived Beta Carotene - E160a (ii) Mixed Carotenes from plant and vegetable sources, typically Palm derived - E160a (iii) Fungal derived Beta Carotene by fermentation of Blakeslea trispora - E160a (iv) Algal derived Carotene from Dunaliela salina

Annatto E160b Bixin (i), Norbixin (ii)

Annatto is a food colour derived from the seeds of the Achiot e tree Bixa orellana. In some parts of the world, Annatto is used for its mild spicy flavour, as well as its intense orange-red colour.

RED

Carmine E120

Primarily grown in South America, Carmine is a bright pink-red colour derived from the female Cochineal beetle Dactylopius coccus, a parasite that feeds on the Prickly Pear cactus.

Red Beet

Red Beet is a natural colour made from the juice of Red Beetroots Beta vulgaris, and is used to create vibrant pink to red shades in food and beverage applications. The pigment in Red Beet responsible for its colour is called Betanin.

Anthocyanins

Red Cabbage
